tpvb or spsipb in pain management after vats

Conditions: Video-assisted Thoracoscopic Surgery; Paravertebral Block; Serratus Posterior Superior Intercostal Plane Block; Regional Anesthesia Morbidity

Summary: the goal of this clinical trial is to compare the analgesic efficacy of thoracal paravertebral block (tpvb) and serratus posterior superior intercostal plane block (spsipb) in patients undergoing video-assisted thoracoscopic surgery (vats). the main questions it aims to answer are: how will the total perioperative opioid consumption of the patients receiving two different blocks change? how will tpvb and spsipb effect the patients' numeric rating scores for pain in the postoperative 24-hour period? how will tpvb and spsipb effect the incidence of opioid related side effects? participants will be divided in two groups: tpvb group will receive a tpvb before the surgery. spsipb group will receive a spsipb nerve block before the surgery. researchers will compare the results between the groups to see the postoperative effects concerning opioid consumption as well as the pain scores, respiratory parameters and opioid associated side effects. the hypothesis of this study is that participants receiving spsipb for vats will have a less total opioid consumption 24 hours postoperatively.

video-assisted thoracoscopic surgeries require a surgical incision of the lateral thoracic wall. in order to ease the postoperative pain of patients undergoing vats, some regional anaesthesia techniques have been tried but there is no consensus on the best method. the gold standard peripheric nerve block is considered to be thoracal paravertebral block (tpvb). recently, a new nerve block called serratus posterior superior intercostal plane block (spsipb) has been described. the anatomic and radiologic studies of spsipb suggest that the local anaesthetic distributes from c7 to t10 vertebrates, covering the surgical site of vats. this study aims to compare the analgesic efficacy of tpvb and spsipb for vats. the hypothesis is that participants receiving spsipb for vats will have a less total opioid consumption 24 hours postoperatively. also, the postoperative pain scores and opioid related side effects of the participants will be recorded. participants will be divided in two groups. the group p will receive a tpvb preoperatively in the operating room. the group s will receive a spsipb preoperatively in the operating room. the participants will be followed 24 hours postoperatively and their total opioid consumption, numeric rating scores for pain, incidence of opioid related side effects will be recorded. also the participants and the surgical teams perioperative pain related satisfaction will be evaluated.
